Lockheed MartinInkampani yaseMelika ebaluleke kakhulu kwimicimbi yezokhuseleko kwi-aerospace, ikakhulu enikezelwe kuphando, uphuhliso kunye nokuveliswa kweenkqubo kunye neenkonzo eziphambili, ibothusile nje umhlaba wokuprinta kwe3D ngokuboniswa kwelungelo elilodwa lomenzi okhethekileyo kuba iinkqubo ezifunekayo ukwenza umshicileli ye yenza iidayimani zokwenziwa phantse kuyo nayiphi na imilo.
Lo matshini mtsha ngewawenziwe ngumqambi UDavid G. Findley Kwaye kunokuba kufanelekile ekwenzeni izixhobo ezomeleleyo ezinje ngeesarha, iimela, ukubhola, kunye nezixhobo ezikhanyayo. Ngokuyintloko, njengoko kubhengeziwe yinkampani yaseLokheed Martin, iya kusebenza Qhubeka nokuphuhlisa iinqwelomoya zokulwa eziphambili zenkampani nangona, amathuba okuba abe nomtsalane ngokwenene kuba inokubakho kwiimarike ezininzi.
U-Lockheed Martin ubonakalisa uyilo lomshicileli wedayimani we-3D
Ukuya kwinkcukacha ezithe kratya, sijamelene nomshicileli we-3D oya kuthi asebenzise i-pre-ceramic filler nanoparticle polymer. Kule nto kufuneka songeze ukuba umatshini kufuneka asebenzise izinto ezimbini eziphambili ze powder yodongwe kunye Polymer pre-yodongwe. Iintloko zeeprinta zifaka lo maleko wezinto ngokobude kude kwenziwe into oyifunayo, ekufuneka ibhakwe kumaqondo obushushu aphezulu. Okokugqibela, kwaye njengesiqhelo, uthuli olungaphezulu komfanekiso kufuneka lususwe.
Umahluko phakathi kwelokishi yeLokheed Martin kunye nezinye iindlela zokushicilela ze-ceramic kukuba ichaza ukubakho kokuprinta izinto ezenza iidayimani zokwenziwa ngenxa yophambi lwayo lwe-ceramic kunye indlela ye-pyrolysis eyona isetyenziselwa indalo yayo.
Njengoko kubhengeziwe ngabo banoxanduva lweprojekthi, enye yeenzuzo zeprinta entsha ukongeza ekuphuhliseni izixhobo ezinganyangekiyo kukukwazi ukuxuba izinto ezinje ngeentlobo ezininzi zeepolymer zangaphambi kwe-ceramic kunye ne-ceramic powders ezidityanisiweyo zinikezela ngeenzuzo ezahlukeneyo zobuchwephesha, ngeeseramiki ukuba inokuxhathisa ukuya kuthi ga kwi-1.400 ºC.
